SentinelOne, Inc. S used its second-quarter fiscal 2027 earnings call to emphasize accelerating AI security demand, platform adoption and better go-to-market efficiency. Management also raised its full-year revenue and operating income outlook.
The Q&A focused on whether emerging products can lift total ARR growth and whether margin expansion can continue alongside reinvestment.
S Builds AI Security Around Runtime Protection
Chief executive officer Tomer Weingarten positioned runtime protection as the core of SentinelOne’s AI strategy to monitor AI workloads and autonomous agents across endpoints and cloud infrastructure.
Weingarten said ARR from Prompt Security and Purple AI tripled year over year in the second quarter. He expects AI security to become the company’s next nine-figure ARR category.
Chief financial officer Sonalee Parekh said the biggest mix shift is occurring in data, AI and cloud. Data posted the fifth straight quarter of ARR growth acceleration, while cloud marked the third.
SentinelOne Raises Fiscal 2027 Outlook
Parekh raised fiscal 2027 revenue guidance to $1.202 billion to $1.207 billion and operating income guidance to $124 million to $128 million. The midpoint implies about 20% revenue growth and a roughly 10% operating margin.
Parekh guided fiscal 2027 non-GAAP EPS of $0.30 to $0.32. Third-quarter revenues are projected to be $309 million to $311 million, with operating income of $38 million to $40 million and EPS of $0.08 to $0.09.
She tied the higher revenue outlook to pipeline strength, platform adoption and improving retention, while noting that enterprise cybersecurity modernization unfolds over multiple quarters and years.
S Couples Growth With Operating Leverage
Revenues rose 21% year over year to $292 million, beating the Zacks Consensus Estimate of $290 million. Non-GAAP EPS of $0.08 topped the Zacks Consensus Estimate of $0.07.
Parekh said ARR rose 22% to $1.218 billion and second-quarter net new ARR reached $56 million, up 4% year over year. The company also posted a record 10% non-GAAP operating margin.
Parekh highlighted more than 900 basis points of year-over-year improvement in sales and marketing expense as a percentage of revenue. RPO reached $1.7 billion and grew 45%.
SentinelOne Pushes Further Upmarket
Weingarten said competitive win rates improved sequentially and year over year, with more seven- and eight-figure wins and record ARR per customer. He highlighted consolidation across endpoint, data, cloud and AI security.
Weingarten said SentinelOne Flex surpassed 10% of total ARR within a year of launch, supporting larger commitments and platform expansion.
A TD Cowen analyst asked why customers with at least $100,000 of ARR grew 13% while total ARR grew faster. Weingarten said larger deal sizes are lifting average revenue per customer even as customer additions moderate.
S Q&A Tests ARR Acceleration and Reinvestment
A Wolfe Research analyst challenged why management was not raising its net new ARR guardrail after a stronger first half. Parekh reiterated that full-year net new ARR should grow year over year and cited retention, pipeline and larger deals behind the higher revenue outlook.
A Morgan Stanley analyst asked how SentinelOne balances growth with margin expansion. Parekh said operating leverage in the platform model allows reinvestment in AI security, data, cloud and stronger sales execution.
An UBS analyst pressed on second-half spending. Parekh said margins should keep improving in the third and fourth quarters, though not at the first-half pace, because guidance includes room for reinvestment.
SentinelOne Leaves Q2 Focused on AI and Efficiency
Weingarten framed AI security as SentinelOne’s top strategic priority and said the company is directing more innovation, go-to-market resources and marketing toward that opportunity.
Parekh kept the financial message centered on durable growth and operating leverage. Management’s posture combines heavier AI investment with a higher revenue and operating income outlook.
S Rank and Style Scores Point to a Mixed Setup
SentinelOne carries a Zacks Rank #3 (Hold). Its Growth Score of B and Momentum Score of B are favorable, while the Value Score of F and VGM Score of D are weaker, leaving the overall Style Score profile mixed.
Zacks Style Scores complement the Zacks Rank, with A and B scores preferred and the strongest combinations typically pairing those grades with a Zacks Rank #1 (Strong Buy) or #2 (Buy). A Rank #3 can still be held, but the Rank can change as analyst estimates are revised after the just-reported results. You can see the complete list of today’s Zacks #1 Rank stocks here.
